The newest reason to get a library card? It could get you into Costco—no membership necessary

Attention, bookworms: What if you could snag the latest SJP book-club pick, stock up on meal-prep essentials, and fill your cart with buzzy natural beauty products all in one fell swoop? If you’re a Costco member, you can already rock this efficient purchasing habit any day of the week, but lucky shoppers in Detroit with nothing but a library card can now gain entry to the buy-in-bulk wonderland.

Here’s the deal: Now through March 18, thanks to a partnership the Troy Public Library, bookworms in the metro Detroit area are granted one-day access to nine southeast Michigan Costco locations—no $120 membership required. To get in, just present this flyer at the door. Bonus: If you do decide to become a member, you can get $10 to $20 dollars knocked off that annual fee (hey, not too shabby).

And in the event that you don’t call Michigan home, no need to fret: Your neighborhood library might be partnering with Costco sooner than you think. Apartment Therapy reported that in November of last year, a similar deal reportedly made bulk-buying dreams come true for Toledo, Ohio, residents—so who knows which destination could be next?

In the meantime, you can still shop Costco online and visit your local library to glean the happiness-inducing effects of curling up with a good read.
